From bc9dacdf9a0f123377f6f97ab23f13f5777e4041 Mon Sep 17 00:00:00 2001 From: Nicholas Nethercote Date: Fri, 11 Apr 2025 06:28:59 +1000 Subject: [PATCH] Move `has_self` field to `hir::AssocKind::Fn`. `hir::AssocItem` currently has a boolean `fn_has_self_parameter` field, which is misplaced, because it's only relevant for associated fns, not for associated consts or types. This commit moves it (and renames it) to the `AssocKind::Fn` variant, where it belongs. This requires introducing a new C-style enum, `AssocTag`, which is like `AssocKind` but without the fields. This is because `AssocKind` values are passed to various functions like `find_by_ident_and_kind` to indicate what kind of associated item should be searched for, and having to specify `has_self` isn't relevant there. New methods: - Predicates `AssocItem::is_fn` and `AssocItem::is_method`. - `AssocItem::as_tag` which converts `AssocItem::kind` to `AssocTag`. Removed `find_by_name_and_kinds`, which is unused. `AssocItem::descr` can now distinguish between methods and associated functions, which slightly improves some error messages. --- src/main_shim.rs | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/main_shim.rs b/src/main_shim.rs index 3b48adb7e918..6eef97c14dd2 100644 --- a/src/main_shim.rs +++ b/src/main_shim.rs @@ -1,6 +1,6 @@ use cranelift_frontend::{FunctionBuilder, FunctionBuilderContext}; use rustc_hir::LangItem; -use rustc_middle::ty::{AssocKind, GenericArg}; +use rustc_middle::ty::{AssocTag, GenericArg}; use rustc_session::config::EntryFnType; use rustc_span::{DUMMY_SP, Ident}; @@ -107,7 +107,7 @@ pub(crate) fn maybe_create_entry_wrapper( .find_by_ident_and_kind( tcx, Ident::from_str("report"), - AssocKind::Fn, + AssocTag::Fn, termination_trait, ) .unwrap();
